The
v
-
sha
p
ed groove is for blades 1/8” wide or
smaller. The flat bottomed groove supports
blades over 1/8” to 3/16” wide. The non-grooved
standard bearing surface at the left is for blades
over 3/16” wide. (The blade provided with your
band saw is 3/4” wide, thus must ride along the
flat non-grooved surface of the bearing, as
shown in Figure 32.)
1. Loosen the socket head cap screw (E,
Figure 29) and push the thrust bearing
bracket laterally to desired position.
2. Re-tighten the socket head cap screw (E).
3. Loosen the locking screw (F) and push the
thrust bearing up to the back of the blade.
4. Adjust the thrust bearing until the space
between the thrust bearing surface (or
groove bottom) and the back edge of the
blade is approximately 0.015” (1/64”). On
the non-grooved surface, a convenient way
to achieve this spacing is by placing a dollar
bill folded twice (four thicknesses of a dollar
bill is approximately 1/64”) between blade
and thrust bearing. If using a groove, set
this distance by eye.
5. Tighten locking screw (F).
6. Make sure all locking screws on the upper
guide bearing assembly are tightened when
adjustments are finished.
Lower Blade Guides
Refer to Figure 33.
1. Disconnect band saw from power source.
2. Open lower door and lower blade guard.
3. Adjust the lower guide bearings and lower
thrust bearing below the table, using the
same procedure and measurements as for
the upper guide bearings and upper thrust
bearing described above.
Movement summary: Loosen locking lever
(G) to move guide bracket using dial (H).
Loosen knob (J) to rotate side bearings,
using (K) and (L). Loosen locking screw (M)
to slide thrust bearing toward blade.
4. Make sure all screws, knobs and lever are
tightened when adjustments are complete.
NOTE: The locking lever (G, Figure 33) can be
re-positioned if needed. Simply pull out on the
lever, rotate it on the hub, and release it. Make
sure it re-seats itself on the hub.
